The great rhombated demitesseract or runcicantic tesseract is a convex semi-uniform polychoron that is a variant of the tesseractihexadecachoron with demitesseractic symmetry. As such it can be represented by x3y3o *b3z, and has 16 truncated tetrahedra (of two types, forms x3y3o and z3y3o) and 8 great rhombitetrahedra (type x3y3z) as cells, with 3 edge lengths.
